there is a significant need for technologies that improve flight safety and reduce maintenance and supportcosts for aircraftturbine engines. the c17 aircraft is being used extensively in the fight againstterror in Iraq and other parts of the world. Engines are being stressed with both high operation temperatures and a severe shorttake off and landing environment. the currentc17 / F117 engines do not have an engine vibration monitoring system. If high vibration conditions occur the flightcrew can not easily identify the problem engine. IAc is developing an airborne turbine Engine Diagnostics System (atEDS) for the c17 / F117 engine. atEDS is designed to automatically collect, process, and monitor vibration datacollected from the F117 engine. In addition to the on-board system atEDS includes a laptop Pc ground based diagnostic system to aid in datacollection, visualization, analysis and fault isolation. Presented in the paper is a description of the atEDS system and preliminary results from collection and processing of t1c17flightdata.
